James wore a sweat-soaked Cavaliers shirt while wrapping his arm around Duchess Kate while she stood posing between the two men. Prince William held a mini jersey with the name of the couple's son, George, on the back, while Kate held one bearing "Cambridge."
Apparently, Kate looked questioningly at LeBron's arm around her, which was there for about 20 seconds.
"The Duchess of Cambridge was very graceful and smiled, even though the look on her face when LeBron James placed his arm around her shoulder speaks volumes about her discomfort of being placed in that situation," Dianne Marsch, the director of the New York Etiquette School of Manhattan, told the Daily News. "Also, Prince William looks down at the jersey, but his body language is speaking volumes of how to handle this situation politely and he even looked away at one point."
"We acknowledge the contribution LeBron James has made to sports, however, he is expected to educate himself according to protocol," Marsch said. "I had mentioned that the body language of the Duke and Duchess of Cambridge would clearly show what is acceptable behavior and no one has the right to trespass into their space."
